Background technology
In the prior art, adopt the technology of noctovisor scan, the infrared radiation of remote measurement rotary kiln shell calculates the surface temperature of trunk according to the intensity of infrared radiation.Scanner scans along the axis that trunk rotates, and utilizes the rotation of trunk self, finishes other direction scanning.After turning over a circle, just obtain the thermal pattern of trunk surface temperature distribution.Scanner of the prior art is provided with one or two reference blackbody in order to ensure the stability of equipment itself in scanner inside, and the temperature of reference blackbody is controlled at some fixed values.Reference blackbody is made of calibrated radiation source.When scanner was worked, the signal of reference blackbody obtained gathering, as the foundation of correction scanner system sensitivity.Using such method can overcome the change of sensitivity that the reasons such as drift of decline owing to infrared eye, electronic circuit cause and the reduction of temperature measurement accuracy, keeps scanner to work steadily in the long term.But because in actual applications, scanner adopts the non-contacting method of telemetering, and the trunk infrared ray enters scanner need pass through a window.Described window is an optics made from the material of transmits infrared; be used to protect scanner inside not to be subjected to outside contamination, interference, damage equipment; but; this window itself be stained with dirt, pollution can influence ultrared seeing through; weaken ultrared intensity, thereby influence temperature measurement result.For example, in manufacture of cement producer, the dirt ash is a lot of, often cover with one deck dust on the window, cause the infrared ray that enters scanner to weaken, temperature value measured is on the low side, and error reaches 40 ℃～50 ℃, also do not send warning when hot spot takes place, have a strong impact on the monitoring effect of scanner performance the trunk temperature.
Summary of the invention
Technical problem to be solved in the utility model is: the inner reference blackbody that is provided with of scanner of the prior art can not compensate the influence of window, influences temperature measurement result.
The utility model is that the technical scheme that solution above-mentioned technical matters of the prior art is adopted provides a kind of infrared ray trunk scanner with means for correcting, described this infrared ray trunk scanner with means for correcting is made of reference source and infrared scanner, be provided with window and data correction circuitry in the described infrared scanner, wherein, described reference source is arranged in the visual field of window of described infrared scanner, the window of described reference source and described infrared scanner is provided with in opposite directions, be provided with temperature sensing circuit in the described reference source, described temperature sensing circuit is connected with signal output apparatus, is provided with telecommunication circuit between the data correction circuitry of described signal output apparatus and described infrared scanner.
Further, described reference source is made of panel and well heater, and described well heater is connected with described panel, and the back side of described panel is provided with insulation material, be provided with temperature element in the described panel, described temperature element is connected with a temperature sensing circuit.
Further again, described well heater is connected with a control circuit, and described control circuit is connected with described infrared scanner by an interface circuit.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is by setting up a reference source in the outside of infrared scanner, temperature reading to reference source compares with the actual temperature value that is provided with, thereby obtain the correction coefficient of scanner temperature reading, then all temperature readings are proofreaied and correct, obtained correct temperature-measuring results.
